[Exim] Eudora and TLS AUTH

I have Andreas Metzler's 4.3 exim-daemon-heavy and gnutls packages
running on a Debian stable machine and am trying to get Eudora (5.2 or
6) to do AUTH over TLS. I have seen the list archives regarding Eudora,
and have tried running exim on 465 with -tls-on-connect, which didn't
work. An stunnel solution won't work because I need my virus scanner to
be able to re-inject mail from the local interface w/o authenticating.

Any time that I try to start a tls session from Eudora, I get these
errors:

2004-02-27 08:57:42 TLS recv error on connection from loki.astro.psu.edu
[128.118.147.196]: A TLS packet with unexpected length was received.
2004-02-27 08:57:42 TLS send error on connection from loki.astro.psu.edu
[128.118.147.196]: The specified session has been invalidated for some
reason.

I have tried using a backported 0.9.7 version of openssl to see if it
would make a difference, but it doesn't. Courier is able to negotiate
tls sessions for imap, so it is either compiled with the SSL_OP options
that work around bugs, or the problem is with the gnutls package that
exim is relying on. Before I compile exim from scratch without gnutls
and move away from the convenience of Debian's update system, I just
want to see if anyone else is running a similar setup and is
experiencing problems with Eudora, or if anyone has found a suitable
workaround.

Thanks

Matt
